IMPROVEMENT In cHURNs'.

The Schedule referred to in. these Letters Patent andmaking part of the same.

ence being had to the accompanyingr drawings, and to the letters of reference marked thereon.

The drawings show a side view of my churn, with a portion of it representedl in section.

This invention consists in so arranging a churn that -it will break up the milk' or cream, and collect the portions forming the butter;l in the shortest time, and in the most thorough manner.'

In construction, I form 1n y churn of a frame, A, having a shaft, B, working in bea-rings a and b at the top and side.

rllhis shaft has a crank, C, on the outside end, and a bevvelled gear-wheel, D, 'ou the other, which operates two smaller gear-wheels; E and F, the one E heilig placedat the top, and attached to a vertical shaft, G, having a dasher, H, at the bottom, andworking iu bearings c at the top of the iiamc.

'lhe gear F is placed at the lower side oi' the wheel l), and is attached to a sleeve, I, around the shaft G.

This sleeve is'shown iu the drawings as if sectioned vertically its length, and has attached to it, at its bottom end, aldasher, J. l

.The sleeve I works in bearings formed in cross-bars K K, and guides the lower part of the shaft G.

The dashers H and J are formed with horizontal arms, ff' and g y', which extend on each side of their shafts.

From these arms extend vertically teeth h h. li, which t in between each other when both dashers are on the same vertical plane, the arms f f', upon the shaft G,

beingl at the bottom, with their teeth extending upward, and the arms y g' above, with their teeth extend ing downward.

The shafts G and I can be taken out of their bearings by means oi' the hinged pieces L L' upon the bars KK, forming one side oi the bearings of the sleeve l.

This is done iu order to place the vessel holding the cream under the frame, and then insertthe dashers..

The operation of this device is as follows:

The vessel containing the cream isplaced under the`- frame. lhe dashcrs are then inserted, thevshatts being set in their bearings, and fastenedin. The crank is turned, revolving the ,gear-wheel D, which turns the smaller wheelslln and F, the one, E, revolving the sllai'tG, and with it the lower dasher, in one direction, while the wheel F turns the sleeve I and upper dasher in the other, the teeth h hl h on the diierent dashers revolving in circles of dit'ereut diameters, and thoroughly breaking upvthe cream.

The gear-wheel I) being made much larger Athan the ones ll and F, a proportionately-incl-cased speed can be obtained upon the dashers over that required in the crank.

By this' means, l obtain a quick, thorough, and cffective method of churning, usinga simple mechanical arrangement, which can be constructed with very'little expense, and, as the dashers of the churn work iu dii'- i'erent directions, the butyraceous particles are more completely collected, anda greater proportion of butter obtained from the amount of cream.

vforming bearings for the shaft I, when used in combination with the arrangementof shafts G and I and dashers H and J, herein described and shown. Y Witnesses: SURVETUS LEAOH.
